located at top of a serpentinized massif; low-temperature (7–9 °C) hydrothermal activity has been provided by direct observation of hydrothermal fluid venting through small orifices in the ocean floor sedimentary cover; deposits on serpentinized peridotite and gabbro; large water column methane anomaly; in MOMAR area, which is designated for long-term monitoring efforts; Aballea et al. (1998) ranked hydrothermal activity as very "possible" in southern FAMOUS segment; not discovered during FLORES cruise (Fouquet et al. 1998); located at south end of FAMOUS segment at axial discontinuity, non-transform offset (NT05); Bougault et al. (1998): "Along the FAMOUS segment, the largest hydrothermal anomalies are recorded along the southern part of the segment with dynamic hydrocast DH 2, from A2 to C2 ... These anomalies seem to indicate a potential discharge area ... about 36°40′N"
